>>In studies by Dr. Rudolph L. Leibel of Columbia and colleagues, when lean and obese research subjects were underfed in order to make them lose 10 to 20 percent of their weight, their hunger increased and metabolism plummeted. Conversely, overfeeding sped up metabolism. This is kind of useless without knowing if they underfed by decreasing amount of food for each feeding time or reducing the numbers of feeding times. The whole idea of eating many small meals during the day instead of a few big ones. Also, depending on the amount of exercising these people are doing these results could go either way.
